Solingen-Weyer, Germany Filed Dec. 1, 1958, Ser. No. 777,271 Claimspriority, application Germany Dec. 6, 1957 1 Claim. 01. 13546) Thepresent invention relates to an umbrella stick and, more particularly,to an umbrella stick for foldable umbrellas provided with spring-urgedlocking members adapted to hold the stick members to be telescoped intoeach other in their end positions.

Heretofore known umbrella sticks for foldable umbrellas have thedrawback that it is rather difiicult to repair the above mentionedlocking members inasmuch as in most instances the top and the handle ofthe umbrella had to be removed in order to be able to pass the innerstick member through the outer wider stick member.

It is, therefore, an object of the present invention to provide anumbrella stick for foldable umbrellas, which will overcome the abovementioned drawbacks.

it is another object of this invention to provide an umbrella stick forfoldable umbrellas, which comprises two stick members adapted to betelescoped into each other and so arranged with regard to each otherthat the stick members can easily be pulled apart for purposes of repairwithout having to remove the top and/ or the handle of the umbrellastick.

These and other objects and advantages of the invention will appear moreclearly from the following specification in connection with theaccompanying drawings, in which:

FIG. 1 is a longitudinal section through the connecting portion of theumbrella sticks when the umbrella is in its pulled-out condition.

FIG. 2 is a cross section through FIG. 1 taken along the line IIlI ofFIG. 1.

FIG. 3 is an axial longitudinal section along the line IIl-III of FIG.1.

The umbrella stick according to the present invention is characterizedprimarily in that in addition to the plug carrying the locking members,as for instance detent balls, there is provided a leaf spring with anabutment pin adapted in the pulled-out condition of the umbrella stickto abut a depression or the like in the outer stick member. At thisabutment point of the abutment pin with the depression in the outerstick member, the outer stick member is provided with a bore throughwhich the abutment pin can be pressed inwardly so that the two stickmembers can easily be completely disassembled.

According to a particularly advantageous arrangement of the presentinvention, the leaf spring may be connected for instance to a V-shapedreinforcing member which is connected to the end of the inner stickmember, for instance by a depression or the like.

Referring now to the drawing in detail, the umbrella stick shown thereincomprises an outer stick member 1 and an inner stick member 2. The outerstick member 1 is in a manner known per se provided with a depression 3which extends into a groove 4 of the inner stick member 2 so as toprevent the two stick members from turning relative to each other. Nearthe lower end of the inner stick member 2 there is arranged a plug 5which may consist for instance of synthetic material and has a bore 6therethrough. Mounted in this bore is a spring 7 acting upon two balls 8and 9. The inner stick member 2 as Well as the outer stick member 1 areprovided with bores adapted to allow the balls 8 and 9 to enter thesame. When the two stick members are pulled apart, the balls will occupythe positions shown in FIGS. 1 and 3 and will .thus hold the stickmembers in their pulled-out positions. In order to allow an easydisassembly of the two stick members, the lower end of the inner stickmember 2 has connected thereto a V-shaped reinforcing member 10. Forpurposes of maintaining the said reinforcing member 10 in its position,it may be provided with a bore 11 (FIG. 2) engaged by a depression 12 ofthe inner stick member 2. The said reinforcing member 10 has connectedthereto a leaf spring 13 for instance by means of a punched-out rivetbushing 14. The upper end of said leaf spring carries an abutment pin15.

From the above, it will :be evident that when the two stick members arepulled away from each other, the said abutment pin 15 will place itselfagainst the end face of the depression 3, thereby preventing a furthermovement of the inner stick member out of the outer stick member. If,however, it is desired, for instance for purposes of repair, todisassemble the two stick members, i.e. to pull the inner stick membercompletely out of the outer stick member, it is merely necessary topress the abutment pin 15 inwardly. This is rather simple inasmuch as inthis position of the abutment pin 15 the outer stick member 1 isprovided with a bore 16. In this way, the two stick members can be takenapart without removing any other parts of the umbrella.

It is, of course, to be understood that the present invention is, by nomeans, limited to the particular construction shown in the drawing, butalso comprises any modifications within the scope of the appended claim.

What I claim is:

In combination in an umbrella stick: an outer stick member, an innerstick member telescopically displaceable in said outer stick member,said inner stick member being movable inwardly relative to said outerstick member from an extended position to a contracted position in whichthe major portion of the inner stick member is telescoped within theouter stick member, said inner and outer stick members havingcooperating detent means engageable to resist relative movement of saidmembers when in said extended position, said outer stick member having adepression extending in longitudinal direction of said outer stickmember over a certain section thereof and forming an internalprojection, said inner stick memher having a longitudinal groove formovably receiving said projection and in cooperation therewithpreventing relative rotation between said inner and outer stick membersin said extended position of said umbrella stick, said outer stickmember also being provided with a transverse bore therethrough adjacentthat end of said depression which is closest to the lower end portion ofsaid inner stick member when said umbrella stick is in its uprightposition, a holding member arranged within and connected to said lowerend portion of said inner stick member, and a leaf spring having one endportion thereof connected to said holding member and having its otherend portion provided with a single abutment member for engagement withsaid lower end of said depression in said extended position of saidumbrella stick to thereby normally prevent extension of said stickbeyond said extended position, said abutment member extending throughsaid bore in said extended position and being movable out of engagementwith said lower end of said depression while said stick is in itsextended position to allow said inner stick member to be fully removedfrom said outer stick member.
